TL;DR: In this article, a detailed description of the third generation atmospheric general circulation model ECHAM is presented, as simulated at low and high resolution (T21 and T42, respectively).

TL;DR: In this paper, the authors compared the observed and modeled stratospheric temperature trends over the past twenty years, from a wide variety of models, with each other and with the observed cooling seen in trend analyses using radiosonde and satellite observations.
Journal ArticleDOI
A comparison of climate response to different radiative forcings in three general circulation models: towards an improved metric of climate change
TL;DR: In this paper, the responses of three general circulation models to distinct forcing scenarios are compared, and they find that their climate sensitivities λ (defined as the ratio of the globally averaged surface temperature change to the radiative forcing), normalised by the climate sensitivity for a control case (e.g. CO2 added globally), match each other to within 30% in most experiments.
Journal ArticleDOI
Contrails in a comprehensive global climate model: Parameterization and radiative forcing results
TL;DR: In this paper, a parameterization of contrails for use in comprehensive global climate models is introduced, based on the thermodynamic theory of contrail formation, which has been applied in a consistent way with the cloud parameterization scheme of the version 4 European Center/Hamburg General Circulation Model.
